Abstract
By configuring a universal wrench with a spanner at one end, and a combined dual piece handle structure, a universal tool is achieved which is extremely useful and versatile. A two piece handle structure includes a removable extension or second handle portion which can be removably attached to a first handle portion. When removed, the wrench is of a relatively compact size, thus allowing access and usability in tight quarters. When the handle portion is combined, the universal wrench has an increased length, thus allowing additional torque to be applied to any bolt or nut being worked on.
Description
UNIVERSAL WRENCH BACKGROUND
[ 01 ] Effective and useful universal tools are desired by mechanics, homeowners, and virtually anyone needing a single tool capable of many different functions. Individuals working on mechanical devices and structures have a continual need to remove and/or attach bolts, screws, nuts, fasteners, etc., and the size of these components is often unpredictable. As such, universal tools and universal wrenches are very useful, since this eliminates the need to have many different tools in a toolbox and on hand at all times.
[ 02 ] In addition to the general utility provided by universal tools, there is often an unpredictable need for various levels of strength and leverage. Obviously, the size of a particular tool will largely dictate its effectiveness and usefulness for a particular purpose. For example, a larger wrench (i.e., longer) can easily provide more strength and leverage when working with fasteners. A larger wrench is not always appropriate, however, especially when working in smaller spaces or with smaller fasteners. Conversely, the use of smaller tools or wrenches may not provide the necessary level of leverage or torque.
[ 03 ] Based upon the issues outlined above, a universal wrench which could be adapted for various situations, provides a useful addition to any toolbox. Such a wrench would provide a single tool which is useful in a wide variety of situations.
SUMMARY
[ 04 ] In various embodiments of the present invention, a universal wrench is provided which is adaptable to many different situations and generally appropriate for the type of work being done. To provide the necessary functionality, the universal wrench has a wrench mechanism (i.e. spanner), capable of interacting with many different fasteners. In addition, a handle structure is provided which can be adjusted to fit the situation. In one embodiment, the handle can easily be separated to a smaller length, when work in tighter spaces is required or a less sizable wrench is desired. Similarly, a longer length handle configuration can be used when additional leverage and strength is required. These features, among others, are generally achieved by utilizing a two-part handle which can be selectively separated, to provide the desired size and strength. A first handle portion is configured to have the wrench mechanism attached to a first end, and a first handle portion on an opposite end. Further, this first handle portion includes a receiving slot on the end opposite the wrench mechanism. The universal wrench also includes a second handle portion having an extension extending from one end thereof. Both the first handle portion and second handle portion have gripping structures to allow a user to conveniently grasp the wrench. Additional features of the second handle portion may be included at an opposite end (i.e. opposite the extension). Most significantly, the extension is uniquely configured to be engaged with the receiving slot. Stated differently, the extension and receiving slot provide a coupling mechanism between these two components. The extension may further include a spring-loaded mechanism to capture and retain the extension in a predetermined position.
[ 05 ] In summary, the universal wrench with a handle structure having two portions, as outlined in the various embodiments described herein, provides an adjustable and useful wrench with the ability to be effectively used for many different situations.

DESCRIPTION OF PREFERRED EMBODIMENTS
[ 14 ] In the description below, and the attached Figures, the features and characteristics of one embodiment of a universal wrench 10 are further outlined.
Generally wrench 10 includes a wrench mechanism, or spanner, 20 which is capable of universally interacting with nuts, bolts, screws and various fasteners of many different types. In addition, wrench 10 includes a handle structure 30 adapted and configured to increase the versatility of the tool. As further detailed below, handle 30 includes a first portion 32 and a second portion 34 to provide additional features and unique capabilities.
[ 15 ] Referring now to the figures, FIG. 1 illustrates a perspective view of the wrench 10 having the features and characteristics described herein. Again, universal wrench 10 includes a wrench structure or spanner 20 situated at one end thereof. In addition, the universal wrench 10 includes a handle 30 designed to allow a user to easily access and manipulate the tool.
[ 16 ] FIGS. 1 - 7 illustrate universal wrench 10 with the handle 30 separated into two components. Referring now to first handle portion 32, a central shaft 40 runs through the middle of a molded handle portion 42. As shown, central shaft 40 is only partially shown at one end, as it has been encased by molded handle portion 42. The central shaft 40 is preferably constructed of carbon steel, while the handle is made of a combination of polypropylene and TPR configured to provide a desired gripping structure.
[ 17 ] Again, attached to a first end of central shaft 40 is the wrench structure or spanner 20. Central shaft 40 also includes a cutout or recess 44 is positioned at an end opposite coupling structure 20. Again, it is understood that a grip structure 42will surround and enclose central shaft 40, while allowing recess 44 to be accessible. As further described below, recess 44 accommodates the attachment of second handle portion 34 when desired.
[ 18 ] As also illustrated in FIGS. 1 - 7, second handle portion 34 includes an extension 50 and a molded grip or handle portion 36. As it clearly illustrated, extension 50 is sized and configured to be received within recess 44, thus creating a removable coupling between these two portions. As will be recognized, extension 50 is part of a central structure (not shown) which exists within second handle portion 34.
[ 19 ] As further illustrated, extension 50 further includes a coupling ball 56 designed to further accommodate the attachment of extension 50 within recess 44. This coupling ball 56 is typically a spring loaded ball, which is simply designed to snap within a related recess within the handle or grip portion 42 (not shown) to hold extension 50 within recess 44.
[ 20 ] As can be appreciated, when second handle portion 34 is attached or coupled with first handle portion 32, the overall length of the universal wrench 10 is increased. This is best illustrated in FIGS. 8-12. Naturally, increased length provides the ability to exert additional force and leverage upon the necessary fastener or connector. Alternatively, when less leverage is necessary, or it is necessary to work in smaller spaces, second handle portion 34 can be removed to provide a more compact universal wrench.
[ 21 ] As mentioned above, first handle portion 32 include recess 44 configured to receive and capture extension 50. At an initial portion of recess 44 a coupling structure 46 exists to provide a more complete, in this particular example, coupling structure 46 includes a hexagonal recess which extends into first handle portion 32 a predetermined distance. A similar hexagonal structure 54 exists at an near edge of shaft 50. As will be appreciated, once shaft 50 is inserted into recess 44, the related hexagonal structure 54 and hexagonal coupling structure 46 will interact with one another to provide a close coupling between these two elements. Most significantly, these related interacting coupling structures will prevent twisting or rotation of first handled portion 32 with respect to the second handle portion 34. As appreciated, this will increase the strength and functionality of universal wrench 10 when in the extended or lengthened configuration.
[22] Various embodiments of the invention have been described above for purposes of illustrating the details thereof and to enable one of ordinary skill in the art to make and use the invention. The details and features of the disclosed embodiments] are not intended to be limiting, as many variations and modifications will be readily apparent to those of skill in the art. Accordingly, the scope of the present disclosure is intended to be interpreted broadly and to include all variations and modifications coming within the scope and spirit of the appended claims and their legal equivalents.
